Markets are manipulated, even with BTC. There is no reason it is valued at what it is, it can move like crazy and drop like crazy on anyone day. If you watch the market and how buy/sells are setup and released you will see manipulation at its finest. There is no way a human can sit there and setup those sells and cancel them to increase or drop the price. It is odd to watch but it happens and there is nothing anyone can do about it except either lose or win.
